Abstract

A bridge expansion joint covering device with high safety, which is used to cover the road surface of bridge expansion joints, comprising a rubber body (9) flush with the level of the bridge road surface, and a rubber body (9) inside the rubber body (9). A support body (8), and two extension supports (7) that can move toward and away from the support body (8) and have a symmetrical structure to each other, wherein the two extension supports (7) Each includes a horizontal extension head (721) capable of sliding horizontally in the chute (81) of the support (8), and a vertical extension (72) connected with the horizontal extension head (721) and a support arm (71) connected to the lower end of the vertical extension (72) and extending toward the adjacent bridge structure, wherein the ends of the two extension supports (7) are provided with The supporting plate (73) against which the adjacent bridge structures abut.

Description

technical field [0001] The invention relates to the field of bridges, in particular to a bridge expansion joint covering device with high safety. Background technique [0002] The pavement of bridges is often provided with expansion joints to provide allowances for thermal expansion and contraction. For the sake of driving safety and maintaining the performance of the bridge pavement, it is often necessary to fill or cover such expansion joints with elastic objects. It is known to cover or pad with materials such as elastic rubber. However, the installation of this elastic rubber material requires further processing such as surface cutting of the base of the pavement in order to install the elastic material in place. And this is easy to cause damage to these processed parts during driving and then damage the pavement matrix. Moreover, the installation and disassembly of this elastic material also requires a lot of manpower and time costs. Contents of the invention [0...
